Hi Grégory,
The scenario description, stack trace and screenshot appear to be related to the following feedback item: https://feedback.telerik.com/Project/154/Feedback/Details/245938-fix-radgridview-having-groups-filters-sort-descriptors-and-search-query-in-t
The observed exception can be reproduced by the asynchronous search in some very specific cases. The comments in the other item provide additional information on why this might happen. We have decided to handle this scenario by introducing a new IsSearchAsync property which is released in the R2 2018 SP1 version of the controls. We have also updated the Search Row documentation: https://docs.telerik.com/devtools/winforms/gridview/rows/search-row. In your actual project please set the RadGridView.IsSearchAsync property to false. In case you keep experiencing the issue please open a support ticket and let us know how it can be reproduced.
Regards,
Dimitar
